function Test-PwshPSHome { <# .SYNOPSIS Returns $true when the current PowerShell session is not running from a Microsoft Store (MSIX) or WinGet installation. .DESCRIPTION Checks whether $PSHOME is located under the WindowsApps directory, which indicates an MSIX-packaged install (Microsoft Store or WinGet). This type of installation runs in a virtualized app container that cannot mount WIM images or access system paths reliably, and therefore does not support PowerShell DISM operations required by this module. Returns $false and emits a warning when a WindowsApps install is detected. Use this test before any DISM or WIM-mount operations. .OUTPUTS [bool] $false when $PSHOME contains '\WindowsApps\'; $true otherwise. .NOTES Author: David Segura Company: Recast Software Install PowerShell 7 from an MSI: https://aka.ms/powershell Dependencies: Executables: dism.exe, winget #> [OutputType([bool])] param () if ($PSHOME -like '*\WindowsApps\*') { Write-Warning "[$($MyInvocation.MyCommand.Name)] This module requires the MSI installation of PowerShell 7.
